3 Claims.

This invention relates in general to containers, and more particularlyto shipping containers of the type in which the body of the container ismade up of bre or other non-metallic material suitable for such use.

The present application is a division of my application for Containenled August 17, 1936, Serial No. 96,351, Patent No. 2,191,705, Feb. 27,1940.

One of the principal objects of th'e invention is to provide a containerof this character which is advantageously combined with metallic endheads, one of which is removable, whereby to adapt a brousbodyrcontainer to many uses and applications to which it would nototherwise be suitable.

Another object of the invention is to so construct the upper removableend head or cover that when the cover is secured in its 'applied orclosed position it will not only be rmly h'eld e in place, but willeffectively and hermetically seal the container and accomplish this insuch manner that even though the container be dropped, and theinterconnected portions of the cover and container distorted, the sealwill not be impaired.

Another object is to provide a container and cover structure wherein thecover may be repeatedly applied to and removed from the containerwithout impairing the integrity of the structure of either or reducingtheir capacity to establish an hermetic seal.

A furher object of the invention is to provide a container constructionin which the' intercrimped or interlocking formations of the end headsand the container ends are practically protected, and wherein theprotecting structure is utilized to facilitate rolling of the container.

A further object of the invention is to provide a construction havingthese advantages and capacities and which is simple in its nature,durable in use, and easily and comparatively inexpensive to manufacture.

Oth'er objects and advantages reside in certain novel features of theconstruction, arrangement, and combination of parts which will behereinafter more fully described and particularly pointed out in theappended claims, reference being had to the accompanying drawing forminga part of this specification, and in which:

Figure 1 is a top plan View of a container constructed in accordancewith the present invention;

Figure 2 is a View thereof in elevation?A Figure 3 is a view in verticalsection taken on line 3-3 of Figure 2, but showing the bendable closurelugs before they are bent into locking position;

Figure 4 is a view similar to Figure 3 showing thelugs in lockingposition;

Figure 5 is a View in section taken on line 5-5 of Figure 2, andillustrating one way in which the lower end head may be interconnectedwith the lower end of the container;

Figure 6 is a View similar to Figure 4 but showing a slight modi'edstructure; and

Figure 'l is a fragmentary View in elevation showing another embodimentof the invention.

Referring to the drawing, and more particularly to Figures 1 to 5,inclusive, it will be seen that in the embodiment of the invention thereillustrated the container comprises a generally cylindrical body portionl which is constituted of fibrous material. The body may be of laminatedfibrous construction, or may be constituted of other non-metallicmaterial suitable for such use.

The lower end of the body portion I is surrounded by and interconnectedwith a closely fitting reinforcing metal sleeve 2, the lower end ofwhich is rolled as at 3 into interlocking engagement with the lower endof the body portion l, the inturned edge 4 of the roll 3 being rmlyforced or embedded into the fbrous body to secure a positive interlockand also a seal. The interconnection of the reinforcing metal sleeve 2and the lower end of the body is enhanced and strengthened by forming anannular inwardly directedv corrugation 5 in the sleeve 2 whichcorrespondingly corrugates the part of the body portion which is engagedtherewith. o

A lower end head or bottom 6 is provided, and adjacent its periphery isprovided with a curved seat 1, which is, of course, annular and engagesa portion of the corrugation 5' in the body portion, whereby the seat 1coacts with the corrugation 5 in interconnecting the metal parts and thefibrous body portion. Below th'e seat 1 the lower end head has anoutwardly directed annular ridge 8, which extends into the annularcrotch between the end 4 of the roll 3 and the adjacent part of thebrous body portion. Beg yond the ridge 8 the lower end head is extendedupwardly, as at 9, and then inwardly, as at Il), into iirm interlockingengagement with the lower part of the sleeve 2 and with the lower halfof the corrugation 5 thereof.

The upper part of the body portion is also surrounded by a reinforcingand strengthening metal member designated generally at I2. This metalmember I2 is also, generally speaking, in the form of a sleeve orcollar, and has a portion I3 depressed inwardly to form the containerwith a reduced upper end or neck. Above the inwardly dished or depressedportion I3 the metal member I2 is folded outwardly and downwardly,providing an inclined flange portion I4, then extended verticallyupwardly, as at I5, then inclined upwardly and inwardly providing aflange portion I6 parallel to flange portion I4, and terminates in arounded or crown-shape portion I'I which is firmly engaged and slightlyembedded in the fibrous body of the container. The sleeve structure I2thus has interlocking formations which securely interconnect it with theupper end of the container.

A removable metallic cover or closure 20 is provided, and has aperipheral portion 2I designed to seat firmly against the inner surfaceof the upper end of the fibrous body and also overlap, to some extent,the crown portion I'I of the metal member I2. Integral with theperipheral portion of the cover is a downwardly and outwardly extendingflange 22. Integral with and depending from the fiange 22 is a verticalannular flange 23. Bendable fastening lugs 24 are integral with anddepend from the lower edge of the flange 23 and terminate at their lowerends in hooks 25. Any suitable number of these fastening lugs areprovided, and they are spaced at intervals about the periphery of theflange 23, as will be understood from Figures 1 and 2.

The flange portion I6 of the metal member I2 provides a seat for agasket 26, which, in the applied position of the cover, is compressedbetween this seat and the ange 22 of the cover to effect completesealing of the container. When the cover is applied to the container thelugs 24 are straight as shown in Figure 3. To firmly secure the cover inposition, and hermetically seal the container, the lugs are bent upunder the shoulder provided by the flange portion I4 of the sleeve-likemetal member I2. This not only secures the cover in position butcompresses the gasket 26 between the flange 22 and the seat I6 so as tohermetically seal the container. The hooks 25 provide a convenient meanswhereby the hooks 24 can be straightened out in order that the cover maybe removed.

It will be seen that as thus constructed the opening at the upper end ofthe container is provided with outwardly and downwardly eX- tendingflanges I6 and I4 which respectively provide a gasket seat and a lockingshoulder. Cooperable with this structure is the downwardly and outwardlyinclined flange 22 of the closure and the bendable lugs 24 thereof.These several parts are constituted of metal suiciently resilient andbendable to preclude their fracture. Moreover, it should be noted thatthe lugs 24 are bent flush up into the angle between the lockingshoulder I4 and the portion I3 of the reinforcing sleeve I2. As a resultof these several features, the closure is not only securely held to thecontainer, but the gasket 26 is compressed to provide a seal, and thisis done in such a way that even though the parts, when assembled, bedistorted under the influence of shocks or blows, the effectiveness ofthe seal will not be impaired. In fact, it will be enhanced.

The form of the invention shown in Figure 6 is identical with that justdescribed except that the crown portion I'I of the metal member I2 isomitted. In this construction the seat for the gasket 26 is constitutedin part by the portion I6 of the metal member and in part by the portionIB of the container. Thus, the gasket seals the juncture of the upperedge of the metal member I2 and the fibrous material.

The present invention also contemplates the provision of outwardlydirected annular corrugations 21 in the reinforcing metal members orsleeves I2 and 2 at the upper and lower ends respectively of thecontainer. Such oorrugations strengthen the construction, and alsoprovide a convenient means whereby the container may be rolled withoutdanger of injury to its ends, or to the means which connects the coverto the container.

While I have shown and described several constructions in which theinvention may be advantageously embodied, it is to be understood thatthese constructions have been selected merely for the purpose ofillustration or example, and thatl various changes in the size, shape,and arrangement may be made without departing from the spirit of theinvention or the scope of the subjoined claims.
